Generation Bio Reports Second Quarter 2023 Financial Results

Second quarter 2023 cash balance of $314.1 million expected to fund operations into 2025

CAMBRIDGE, MASS., Aug. 2, 2023 -- Generation Bio Co. (Nasdaq: GBIO), a biotechnology company innovating genetic medicines for people living with rare and prevalent diseases, reported business highlights and second quarter 2023 financial results.

“We continue to make encouraging progress in the development of our cell-targeted lipid nanoparticle (ctLNP) technology, which is a unique, highly specific, non-viral genetic medicine delivery system for nucleic acid cargoes targeted to the liver as well as non-liver tissues,” said Geoff McDonough, M.D., chief executive officer of Generation Bio. “For the remainder of the year, we are focused on demonstrating Factor VIII expression in non-human primates for our hemophilia A program as well as continued development of in-vivo targeting to immune cells with our stealth ctLNPs. These achievements are important for demonstrating our platform’s potential to enable a deep pipeline of hepatic programs and broad portfolios of extrahepatic programs.”

About Generation Bio

Generation Bio is innovating genetic medicines to provide durable, redosable treatments for people living with rare and prevalent diseases. The company’s non-viral genetic medicine platform incorporates a novel DNA construct called closed-ended DNA, or ceDNA; a unique cell-targeted lipid nanoparticle delivery system, or ctLNP; and a highly scalable capsid-free manufacturing process that uses proprietary cell-free rapid enzymatic synthesis, or RES, to produce ceDNA. The platform is designed to enable multi-year durability from a single dose, to deliver large genetic payloads, including multiple genes, to specific tissues and cell types, and to

allow titration and redosing to adjust or extend expression levels in each patient. RES has the potential to expand Generation Bio’s manufacturing scale to hundreds of millions of doses to support its mission to extend the reach of genetic medicine to more people, living with more diseases, around the world.
